Increment values every .25 in a for loop

[eldan88]

Hey Guys. I am trying to add a tip function on a resturants online ordering page. I am having trouble incrementing the value .25 cents. Does anyone have any suggestions on how to do this.

 

All help would be really appreciated.. below is what I have so far.

<select>
<?php
for($tip=0.00; $tip<=11.75; $tip++){
 echo "<option value=\"$tip\">"."$".$tip ."</option>";
};
?>

</select>

$tip++ is shorthand for $tip = $tip + 1.

Hey Requinix. Oh okay. I never knew that! I changed the following statement to this

 

$tip=0.00; $tip<=11.75; $tip+=0.25

 

It works on the browser, but it doesn't show the  zero change is .50 cents.

For example it would show

 

2.5

not 2.50

 

Would you know how to change that? Here is my code again

<select>
<?php
for($tip=0.00; $tip<=11.75; $tip+=0.25){
 echo "<option value=\"$tip\">"."$".$tip ."</option>";
};
?>
</select>

I always read the manual. But how do you expect me to pin point the exact PHP function for the question I asked requinix?

I will read more of it tonight and have a nice romantic evening with it....haha

You can't honestly say you made a real effort to find the solution yourself. If you Google any number of things you would have found the answer in about 20 seconds: "php format number" "php show number as currency" "php number trailing zeros", etc.

googling "php format string" gives that function as first result.

 

googling "php format number" gives another alternative number_format.

 

 

It's literally as easy as typing in exactly what you ask here. I'm not trying to be a douche and I'm trying to give you the benefit of the doubt, but I'm starting to get the impression that you're treating us like your personal google service.

No not at all. That's the last thing I would ever want to do. I know you guys are helping me for free, and would never want to take advantage. 

I'm just really passionte about this stuff and thought you guys can help me.

 

But you guys are right. I will try to look up these simple questions on google, then coming here and  asking away. 

 

I do want to thank you guys for trying to help me. It means alot.
